Early each spring in Antarctica, when the sun crests the horizon after the long dark winter, ozone begins to disappear in the atmosphere high above the continent. Within a few weeks, so much ozone disappears that a “hole” forms in the ozone layer there. Learn why and how the ozone hole develops and its consequences not just for life at the bottom of the world, but for the entire planet.
